The dataset, titled 'census2000.csv', consists of four columns: 'Sex', 'Year', 'Age', and 'People'. It captures the population distribution across different ages for the years 1900 and 2000, differentiated by sex. The data includes counts of people for various age groups, segmented by gender and collected at two century intervals.
1. How does the population distribution by age differ between the years 1900 and 2000?
2. What is the gender distribution for different age groups in the year 2000?
1. A line graph to compare the population distribution by age for the years 1900 and 2000. It aims to illustrate trends and shifts in the population over the century.
Rationale:
To compare the population distribution across different ages for the two years.
A line graph can effectively show trends and allow for easy comparison between the two years.
It would highlight any significant demographic shifts or trends over the century.
2. A stacked bar chart representing the age distribution by gender for the year 2000. It provides insights into the composition of each age group with respect to gender.
Rationale:
To visualize the composition of each age group by gender in a specific year.
A stacked bar chart can show the total population while also providing insights into the gender ratio within each age group.
It helps in understanding the balance or disparity between different genders in various age groups.
3. A grouped bar chart to compare the number of males and females across different age groups for the year 2000. This facilitates a direct comparison between genders for each age group.
